The Policy Research Working Paper 10753 discusses the challenges in identifying green occupations and the skills required for them. The paper presents an organizing framework for existing definitions, measurement instruments, and policy frameworks related to green jobs. It then discusses two approaches for identifying green occupations: the task-content and the skills approaches. The paper introduces a novel methodology using a dictionary of green terms to identify green tasks and occupations. The findings of this paper can be useful for policymakers and practitioners designing skills development policies for the green transition.
